BUFFER.

Specification of Letters Patent.

Patented Apr. 24, 1917.

Application led April 21, 1916. Serial No. 92,754.

To all whom it may concern.'

Be it known that I, WILLIAM H. ASPEGREN, a citizen of the United States,residin at Quincy, in the county of Norfolk and tate of Massachusetts,have invented new and useful Improvements in Buers, of which thefollowing is a specification.

This invention relates to buffers for doors, windows or the like, theobject of the invention being to provide a cheap, simple device capableof being applied preferably to the jamb of a door frame, but which canbe applied equally well to the door itself for the purpose of absorbingthe shock and reducing the sound as the door is closed and to preventvibration after the door has been closed and latched.

My invention is extremely simple, very effective, inconspicuous and veryeasy to attach.

The invention consists in certain novel features of construction andmethods of application which are hereinafter fully described in thespecilication and particularly pointed out in the claims.

Referring to the drawings:

Figure 1 is a combined front elevation and plan view of my preferredform of buffer, the same being shown upon a somewhat enlarged scale.

Fig. 2 illustrates the buffer, practically of normal size in frontelevation attached to the jamb of a door frame.

Fig. 3 is a transverse section through a portion ofa door and doorframe, illustrating the buer applied to the j amb of the door frame withthe door closed against the buffer.

Fig. 4 illustrates the buffer in plan view as applied to a screen door,a portion of the door, together with the door frame, being shown insection.

Fig. 5 is an enlarged front elevation of the positioning member.

Fig. 6 is a View similar to Fig. 4 with the positioning locking memberapplied thereto.

Like numerals refer to like parts throughout the several views of thedrawings.

In the drawings, 12 represents a section of a door frame or jamb and 13a section of a door. My improved buffer 14 shown clearly in detail inFig. 1 is capable of being attached to either the door frame or door ina number of different ways to meet varying conditions. In Figs. 2 and 3it is shown located in the rabbet 15 of the door frame l2 to which it isfastened by a nail 16. The buffer 14 consists of a piece of resilientmaterial 17 such as rubber, felt or the like adapted to act as a cushionbetween the door 1 8 and the frame 12 to absorb the shock and reduce thesound as the door is closed. The piece of rubber or felt 17 is mountedupon a wire 18, preferably by first forming said wire in the shape of astaple and forcing the parallel arms 19 of said staple through saidmaterial 17. The arms are then bent to form two oppositely disposedV-shaped wings 20, after which the ends 21 of the wire are bent aroundan eyelet 22 having flanges 23 adapted to keep the ends 21 of the wirefrom spreading and to hold the eyelet 22 firmly clamped in position.

The nail 16 passes through the eyelet 22 and is driven into the frame12. By shaping the wire 18 as lhereinbefore mentioned in the form ofoppositely disposed V-shaped wings 20, an adjustable, flexible supportis formed capable of yielding when the buffer is attached to a door 24,as illustrated in Fig. 4, and coperating with the cushioning material 17to absorb the shock.

It is evident that should the buer be attachedv to a very thin door itmight be necessary to reduce the distance between the eyelet 22 and thecushioning material 17, therefore by bending the wire slightly to changethe angle of the V-shaped wings, as illustrated in dotted lines, Fig. 1,the distance between the eyelet 22 and said cushioning material 17 maybe greatly reduced, while the wire 18 will still retain its iiexibility.

In Fig. 6 I have illustrated the bulfer'l-l applied to a door 24 whichcloses against a frame 25 upon which there is no groove as is often thecase with screen doors. At such times I find it advisable to use a posi-'tioning or reinforcing member 26 clearly illustrated in Fig. 5 andformed of wire 27. One end 28 of the positioning member 26 is adapted toengage the parallel arms 19 of the buer 14 adjacent to the resilientmaterial 17, while the ends 29 of the wire are bent around and hold aneyelet 30 similar to the method by which the eyelet 22 is held.

A nail 31 attaches the locking member to the door 24. It will thus beseen that the positioning member 26 will at all times hold the buifer 14in its proper position upon the door 24.

The method of operation of my improvedbuer is as follows:

The buffer 14 is fastened preferably in the rabbet 15 of the door frame12, Fig. 3, but

it is evident that said buffer could be applied equally well to thecorner A of said frame or to the corner B of= the door 13.

The door 13 closing in the direction of the arrow a will close againstthe resilient material 17 in each instance, which will act as a cushionto absorb the shock and reduce.

the sound of the door as it closes.y If applied toa door as in Fig.4,.the doon 24 closing in the direction of the arrow b will compress theresilient material 17 and also cause the eXible wire 18 to yield;

It will thus be seen that in this V'instance the resilient material 17and the iexible wire 18 will cooperate to absorbthe shock of the closingdoor. In Fig. 6 where. there is no opportunity to locate the buffer inthe rabbet of the door frame thepositioningy member 26 is used inconjunctionw-ith the buffer 14 as hereinbefore described.

It will be seen that in each of the'different forms of my inventionhereinbefore' de scribed the buffer consists of anranglemember havingtwo sides, one of which isl for-med of a piece of resilient materiallandthe other side, projecting therefrom at. substantially- Having thusdescribed my invention what I claim and desire by Letters Patent tosecure is: v l

1. A buffer comprising a resilient member, means'forattaching saidresilient member to a door or door frame, said means extendingsubstantially at right angles to said resilient member, and apositioning member engaging said attaching means and 'extend-V ing-atright anglesthereto, said positioning member adapted to be fastened tosaid door or door frame.

2.v A buffer comprising an angle member, one side of said angle memberconsisting of a flat piece of resilient material, the other side of saidangle member consistingv of a @shaped-wire, the legs of said Ui-shapedwire passing throughv said: piece of resilient material and forming`V-shaped wings whereby said piece of resilient material may befastenedeither toa door or door frame, two sides of said angle member beingadapted to simultaneously contact with the two .sides of a right angledrecess and also to ycontact simultaneously with the edge and one face ofa door t0 which it be attached.

3. A buffer comprising aresilient shock andl sound absorbing' member, aU-shaped wire,the legs offsaid U-shaped wire passing through saidmember, oppositely disposed Vshaped-wings formed'by said legs,\aneyelety atV the extremities of saidV legs, means passing through saidIeyeletv adapted- 4to fasten saidbuffer toa door frame or door,-

and a positioning member adapted toengage said buffer' and coperatewithI said fastening: device to 'attach said buffer toV said door'frameor'door.

In testimony whereof I have hereunto set my hand in presence of twosubscribingwit'- nesses.-
